Acti9 iID Differential 4P 63A 500mA Class B SI

The Schneider Electric Acti9 iID 4P 63A 500mA Class B-SI differential switch, reference A9Z66463, is an advanced protection solution designed for environments where high reliability and electrical safety are required. This differential is equipped with Class B-SI (super immunized) ground fault protection technology, making it ideal for applications that include photovoltaic systems, where conditions can be more demanding due to continuous and variable residual currents. Additionally, it offers instantaneous leakage protection with a sensitivity of 500 mA, ensuring effective protection for people and equipment in alternating current (AC) systems.

Applications:

The Acti9 iID 4P 63A is ideal for protecting electrical circuits in residential, commercial, and industrial installations, especially in photovoltaic applications and other systems where non-linear loads or electronic equipment may generate more complex leakage currents. It is also suitable for power distribution systems that require an additional level of immunity against interference and voltage spikes, providing extra safety in sensitive applications.

Main features:

• Rated current of 63A and 4 poles: This differential switch is designed to handle up to 63 A, providing robust protection for electrical distribution circuits. Additionally, the device features 4 poles, allowing for more comprehensive control over three-phase circuits with neutral.
• Sensitivity of 500 mA: With a sensitivity of 500 mA, the differential can efficiently detect ground faults, instantly disconnecting the circuit to prevent damage or potential hazards, while its high immunity to electrical disturbances makes it especially suitable for installations with sensitive electronic equipment.
• Class B-SI (super immunized): This classification ensures that the differential offers superior performance in environments with complex electronic loads or continuous residual currents. Class B provides protection against alternating (AC), pulsating, and smooth continuous currents, making it an ideal choice for photovoltaic applications and other installations with variations in leakage currents.
